如何在PHP中显示MySQL Select语句结果(How to display MySQL Select statement results in PHP)

我有下面的代码，它应该从mysql表中返回一个值（id）。 下面的代码不起作用。 我怎样才能输出它，而不创建数组和所有这些东西，只是一个值的简单输出。

$query = "SELECT id FROM users_entity WHERE username = 'Admin' "; $result = map_query($query); echo $result;

I have the following code and it should return just one value (id) from mysql table. The following code doesnt work. How can I output it without creating arrays and all this stuff, just a simple output of one value.

$query = "SELECT id FROM users_entity WHERE username = 'Admin' "; $result = map_query($query); echo $result;

最满意答案

我做这样的事情：

<?php $data = mysql_fetch_object($result); echo $data->foo(); ?>

你必须做一些形式的对象创建。 没有真正的解决方法。

I do something like this:

<?php $data = mysql_fetch_object($result); echo $data->foo(); ?>

You have to do some form of object creation. There's no real way around that.
